Washington optioned Suero to Triple-A Rochester on Saturday.
Suero forked over his spot in the Washington bullpen to Tanner Rainey, who was called up from Rochester in a corresponding move. Though the 30-year-old right-hander has struggled for much of the 2021 campaign, his demotion still comes as a surprise. Suero had been sharp over his last five appearances, giving up two runs (one earned) on three hits and a walk while striking out eight over 5.2 innings.
